Summary: The ultra-weak chemiluminescence of Fenton system can be enhanced by phosphorus and chlorine co-doped carbon dots (PClCDs) or eosinY (EY). The synergistic enhancing effect of PClCDs and EY on the CL emission of Fenton reaction provides a stronger and more efficient CL system. Methionine (Met) is found to effectively diminish the CL intensity of PClCDs-EY-Fenton system, with a linear dynamic range of 0.1-10.0 mu M Met concentrations under optimal conditions.

Summary: Two spectroscopic methods were developed for quantifying oxybutynin hydrochloride, dependent on ion-pair complex formation between the drug's tertiary amino group and eosin in acetate buffer. The methods showed linearity in a specific concentration range, and greenness and speed were highlighted as potentials compared to other reported methods. Further investigation into quenching mechanism and reaction pathway was conducted to provide insights into the methodology.

Summary: In this study, a fluorescence sensor based on molecularly imprinted cysteine-modified Mn2+: ZnS QDs (MIP@ZnS QDs) was successfully developed for rapid detection of dopamine hydrochloride. The MIP@ZnS quantum dots showed rapid response, high sensitivity, and selectivity for dopamine hydrochloride molecules. The sensor demonstrated good linear response and a low limit of detection, and it was successfully applied for detection of dopamine hydrochloride in urine samples. The MIP@ZnS QDs based fluorescent sensor provides a promising approach for food safety detection and drug analysis.

Summary: This study demonstrates the photovoltaic properties of Eosin-Y dye-sensitized N-doped TiO2 photoanodes. N-doped TiO2 photoanodes were prepared using the sol-gel method followed by specific treatment. These photoanodes were then analyzed using various techniques. The results show that N doping leads to lattice disorder effects and the formation of midgap electronic states, resulting in a narrowing of the energy band gap. The presence of a large porous structure, which provides optimal visible light absorption and dye absorption, is considered crucial for achieving good photovoltaic performance.

Summary: Aggregation-induced emission (AIE) is a unique phenomenon that revolutionizes luminescence. However, the research on AIE has been limited to a few molecular structures, hindering in-depth studies and exploitation of their potential values. In this study, a novel dumbbell AIE skeleton is reported, which overcomes the challenges of difficult modification and low luminous efficiency. The skeleton exhibits strong solid-state emission and diverse modification possibilities, making it applicable in various scenarios.

Summary: Eosin Y, a commonly used dye for cotton and silk, is highly toxic and difficult to degrade. Around 20% of it becomes organic dye wastewater during the printing and dyeing process, posing serious harm to the environment and human health. In this study, naturally oxidized pyrite was chosen as a promising photocatalyst to degrade Eosin Y, achieving over 90% degradation under specific conditions.
